Chris' Tips
DISCONTINUED - This HiTorque Mini Mill has been replaced by the 3990 HiTorque Mini Mill, Solid Column with Air Spring.

You can compare the specifications for our mills.

Mini-Lathe.com has a review of our solid column mill.

The solid column is much more rigid than the tilting column.

Some people may feel that the tilting column is a feature, but I have used a mini mill for 10 years and never tilted the column on purpose.

Let's compare the LittleMachineShop.com Solid Column HiTorque Mini Mill to mini mills with a tilting column.

The tilting column on other folk's mini mills tilts 45 degrees from side to side. This has several advantages. First, it is possible to make some angled cuts. It's also easy to tram in the X-axis. One user (and only one) has described to me a cut that was impossible to make any way but using a tilting column.

This mill has a solid column. While it is harder to tram in the X-axis because you must use shims, it is not as easy to knock it out of tram as the tilting column mini mill. The solid column has thicker walls than the tilting column, and a stiffer joint where it joins the base, so the column is significantly more rigid than the tilting column.

LittleMachineShop.com no longer sells mills with a tilting column. That is an indication of how much better the solid column is.

The LittleMachineShop.com HiTorque Mini Mill does not come with a drill chuck as many other mini mills do. That's because the drill chucks provided by the factory do not meet our quality standards (read: they're junk). We had them put the value of the drill chuck into other parts of the mill, like the large X-Y table that is unique to LittleMachineShop.com.

Get one of these drill chucks and you will be in business.

Here are data sheets for the machines that we sell.

Here's what you need to convert the HiTorque Mini Mill to CNC. (But be sure you look at the CNC milling machines that we sell before you start).

Here are the user's guides for our machines.

Shipping

March 1, 2022 - Recent and unprecedented price increases in truck freight and gas prices, especially to residential addresses, has required us to increase the cost of our truck freight. We hope the future will see a return to normal and historical costs, but until then freight delivery costs have increased.

These machines ship by truck because they are simply too heavy and bulky for UPS Parcel Service. We normally ship truck orders a day or two after we receive the order. We add the following shipping cost to your order total:

We ship machines only to the US and Canada.

Destination	*Local	Continental US
Freight Terminal (pick-up) Within 50 miles / 1 hour of travel Note: Not all terminals allow pickup	$150	$175
Commercial Address & Limited Access Sites Set hours / No delivery appointment Includes limited access (e.g. Schools, Military, Gov. Bldgs) Does not include liftgage service**	$99	$175
**Liftgate: Add liftgate if forklift or loading dock is not available onsite.		+ $75
Residential Address Includes delivery appointment and liftgage for ALL Residential businesses	$99	$270

*Local refers to the parts of Southern California served by Hollywood Delivery Service.

**Liftgate service is included in local delivery and residential delivery. A loading dock or forklift is assumed in commercial deliveries. If these are not available, please add this extra service.

Additional Notes

Contact and delivery. Ensure you choose the correct type of delivery, have a dedicated contact person/number, and are ready on day of delivery. Freight companies charge an additional fee if delivery exceeds 30 minutes.
Only one shipping charge for entire pallet (up to 700 pounds total). The shipping charges shown above cover the cost of shipping the machine and anything else that you purchase with it, including a second machine, stand, tooling, and accessories.
A "commercial address" has a sign with company name, a public entrance and posted hours of operation. If you are running a business at your residence without a public entrance and posted company name and hours of operation it is considered a residence and a not commercial address.
A "limited access" designation is required for "Secured Locations" (schools, colleges, universities, university hospitals, military bases, government facilities, etc). Please provide accurate details on delivery in special instructions.
"Terminal Pickup" allows for pickup at local terminal. If there is not a terminal within 50 miles (or 1 hour), we will confirm with you that you still want Terminal Pickup. Terminals tend to be near highways (usually miltiple intersecting) and industrial centers. Only certain terminals allow pick-up.
"Residential delivery" does not include moving machine into home/garage/workshop or any setup. Delivery is to start of driveway on the street that the delivery truck can access. (See inside delivery below.)

For delivery to Alaska, Hawaii, or Puerto Rico

We will check with several trucking companies to get the best price and then call for your approval before we ship.

Canadian Shipments

Truck Freight shipping to Canada involves 3 distinct charges in addition to the product costs. (All amounts are in US Dollars, see the current mid-market exchange rate.)

Canadian Provincial Taxes (GST, PST, HST) depending on which province the shipment is going to. This will be 5% - 15% added to total sales amount depending on province (Canadian Sales Tax).
Hemisphere Customs Brokerage which handles all customs clearance requirements. This is a flat fee of $108 on any shipment.
Truck Freight from Southern California to destination in Canada. This is generally $300-$500 for residential liftgate delivery and appointment for single machine + tooling orders. Delivery to a terminal for pick-up or a commercial location with loading capabilities can reduce this cost substantially.
